Target drivers must guarantee that struct se_cmd and struct se_tmr_req exist as long as target_tmr_work() is in progress. Since the last access by the LIO core is a call to .check_stop_free() and since the Xen scsiback .check_stop_free() drops a reference to the TMF, it is already guaranteed that the struct se_cmd that corresponds to the TMF exists as long as target_tmr_work() is in progress. Hence change the second argument of transport_generic_free_cmd() from 1 into 0.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
